ARTIFICIAL WHEAT-STRA'W BRAID.

Application filed February 23, 1924..` Serial No. 694,813.

This invention relates to imitation of vstraw braids, and consists inpasting on one or both sides ol white thin paper shavings of populusalbo or any other grainless wood, which is dyed in any desired colour,coating the shaving thus dyed and lined, with nitrocellulose or anyother cellulose ester solution, cutting it into tapes of any desiredwidth, and plaiting them into braids. The object of this invention is toobtain goed material for summer hats, &c. which is cheap, does noteasily 'tear olf, and closely resembles in its appearance to naturalstraw braids.

Hitherto shaving is commonly used as 1naterial for hats, but no attempthas yet been made to make it appear like straw. It receives no treatmentother than bleaching, and consequently it retains all its woodyappearance, and is glossless. It easily splits, and being devoid ofwaterproof property, easily gets soiled. f

Now, in this invention the film of nitrocellulose, or any othercellulose ester, gives to the shaving a horny look, and together withthe white paper pasted on the reverse side, gives it gloss andappearance that cannot be easily distinguished from straw. This is dueto the white paper pasted on the reverse side shining through theshaving and lilm of nitrocellulose, or the like.

Tapes in this invention are cut` into any desired width, and thereforethere is no trouble ol" asserting them. They are less diiiicult inbleaching and do not lade by exposure to the sun. Especially, as theyare tough, flexible and are not easily torn on, they are an idealmaterial for hats and bonnets. The following is a more lull descriptionof my invention, reference being` had to the accompanying drawing. Inthe drawing Fig. l is a view of shaving pasted on paper and coated withsolution of nitrocellulose or any other cellulose ester; and

Fig. 2 is a section thereof.

Fig. 3 is aview of the shaving eut into tapes, and

Fig. 4l is an example of such tapes plaited into a braid.

In the figures, (l) is a long continuous Japanese paper on one or bothsides of which are pasted with a waterproof paste shavings oit populusalbo or any other suitable wood, either bleached or unbleached, and dyedwith a dye, ,or pigment, into light yellow colour so that they presentan appearance resembling to the straw. Shay ings thus pasted are thenkcoated with nitrocellulose, dissolved in a solution of camphor inalcohol, rthus forming a transparent, smooth and kglossy surface asshown at (3). This is cut into tapes (Ll), which are plaited into abraid as shown in Fig.

ln this invention, if the shaving is pasted only on one side of paper,the tapes will have an appearance of straw split, the paper representingthe white inner layer, and'ii it is pasted on bothsides, the tapes lool;like straw flattened without splitting.

I claim:

l. As an article oi manufacture, artificial straw comprising tapes cutfrom material composed of a thin white paper and thin wood shavingspasted on the paper parallel with the length of the tape, and coatedwith a solution of a cellulose ester.

2. As an article of manufacture, artificial straw comprising tapes cutfrom material composed of thin white paper and thin wood shavings,pasted on both sides of the paper, and coated with a transparentvarnish.

As an article of inanuilacture, artilicial straw comprising tapes cutfrom nmterial composed of thin paper and thin wood shavings ofgrainlesswood previously coloured, pasted on the paper, and then coatedwith a solution ot cellulose ester.

In testimony whereof have signed my name to this specilicaton.
